Hi
recently bought a new aquarium,have set it all up and want to do a fishless and ammonia free cycle.
It has been running now for 2weeks,have added filter start,cranked heat up and even used bit of fish food occasionally.
Tested water today ammonia is at 0.50ppm
nitrate is at 20ppm
nitrite is at 0
Please can someone advise me if this is normal? When its safe to put fish in etc,would be very greatful for any advice
Thanks
Mark.
